How to Make Your In-memory NoSQL Datastores Enterprise-Ready
In-memory NoSQL datastores such as open source Redis and Memcached are becoming the de-facto standard for every web/mobile application that cares about its user’s experience. Still, large enterprises have struggled to adopt these databases in recent years due to challenges with performance, scalability and availability. ... This article will outline how to make an in-memory NoSQL datastore enterprise-ready, with tips and recommendations on how to overcome the top seven challenges associated with managing these databases in the cloud.


Virginia Tech breach exposes data on 145K job applicants
"The server was placed in service without our normal cyber protection protocols," thereby allowing illegal access to the data, Hincker said in an email. The university said the oversight allowed someone to illegally access the server and potentially the data it contained. "We became aware on Aug. 28 that it had been compromised," Hincker said without elaborating on how the university discovered the problem. In many cases, such data compromises go unnoticed until the breached entity is notified by law enforcement, credit card companies or victims.


Uses for Hadoop: Exploring the storage, appliance and analytics options
Hadoop can be a beneficial tool for big data environments, but according to John Webster, a senior partner at Boulder, CO-based Evaluator Group Inc., a lot of the criticism stems from a lack of understanding of the uses for Hadoop. In the first of this two-part podcast, Webster explains Hadoop's role in data storage, whether it can be used as an alternative to object storage and what needs to change to spread Hadoop adoption. Listen to the podcast or read the transcript below.


Are You a High-Performer--or Just an Overachiever?
An overachiever can ram through a new marketing strategy. They can wear down a recalcitrant team member. They will outlast a recession, explode past their competition, annihilate technical constraints. This all looks good from a distance, but up close, internally, it’s tearing muscle from bone, weakening the business. Performance-based leaders, on the other hand, deliver results while building up the business, not weakening it. Like the overachiever, they make things happen, but at the same time, they make their organization better, fitter, more growth-oriented, rather than weakening it.


Value-Based Health Care Is Inevitable and That’s Good
Data can help identify variations in clinical practice, utilization rates, and performance against internal and external benchmarks, leading to improved quality and a sustained change in culture. Last year, we established a values-based care team, which seeks to eliminate unnecessary practice variation by developing evidence-based care paths across diseases and to improve comprehensive care coordination so that patients move seamlessly through the system, reducing unnecessary hospitalizations and ER visits.


Look before you leap: Evaluating cloud migrations in high-performance LAN environments
On paper, cloud looks great. You're going to save a bundle of money, have less headaches to deal with, less systems to manage, etc. But you suspect that if you move your systems and data that run at LAN speeds to the cloud, productivity could grind to a proverbial halt. But at some point, you may need to prove it to senior management, and, “I’ve got a bad feeling about this,” probably won’t cut it, Han. Besides, don’t you really want to know for sure before putting up a fight?


Neural Network Data Normalization and Encoding
A topic that's often very confusing for beginners when using neural networks is data normalization and encoding. Because neural networks work internally with numeric data, binary data (such as sex, which can be male or female) and categorical data (such as a community, which can be suburban, city or rural) must be encoded in numeric form. ... This article explains how to normalize and encode neural network data from a developer's point of view. The process is conceptually simple but surprisingly difficult to implement.


Cisco reveals its Internet of Everything router
The system is not a core router like the Cisco CRS, or a successor to the CRS, the company says. Rather, it is a network fabric designed to scale CRS cores and ASR 9000 edge routers in service provider networks from centralized systems to distributed architectures able to accommodate the growth of Internet connected "things," like cars, homes and machines.


Better Agile Adoptions
Usually, the following pattern is used to implement Agile methods, usually after a small pilot test of Agile with a small team: Authority says we are all “going Agile”; Authority says we will be using a specific practice, like Scrum, or Kanban, or some other Agile practice, method, or framework. The message is that this is not negotiable; Authority selects a coach on the basis of his or her expertise with the prescribed practices. Typically, Scrum skills. The coach is imposed on the people, just like the prescribed Agile practices.
